Well, for what its worth, my single 15 sounds great with about 3K watts daily and I like to bang it often! I got a 141DB test out of it BEFORE I got the batts all hooked up and its MUCH louder now and the SQ is really good too really smooth but also hits HARD for the kick drum stuff, rock, rap, Pink Floyd....It all sounds great! AQ is the way to go in my book. My setup is every bit as loud as my brother in laws single Death Penalty 18 was in an SUV and better with the rock stuff to boot! Just a suggestion. The AQ will easily take the power, just get the aluminum coil..
